Step-by-step explanation:
You'd do 80% times 32. You have to move the 80 to the left 2 times. then multiply.
Answer:
Step-by-step explanation:
Using either the critical value rule or the p-value rule, a conclusion can be drawn at a level of significance (alpha)
The null hypothesis: u = hypothesized mean
Alternative hypothesis: u > u0 or u < u0 for a one tailed test
Alternative hypothesis for a two tailed test: u =/ u0
To draw a conclusion by failing to reject the null hypothesis as stated then: using critical value
Observed z score > critical z score for both the one and two tailed test.
Or using p value:
P-value > alpha for a one tailed test
P-value > alpha/2 for a two tailed test
Thus, if a one-sided null hypothesis for a single mean cannot be rejected at a given significance level, then the corresponding two-sided null hypothesis will also not be rejected at the same significance level.
Answer:
-4c-6
Step-by-step explanation:
-4c+(-6)-4c-4c
Group like terms
-4c-4c-4c-6
-8c-4c-6
-4c-6
So assuming that x2=x^2 and not 2x
3(7+2^2)
3(7+4)
3(11)
33
